BOSTON– As Senator Scott Brown attends the White House bill signing of his STOCK Act banning insider trading among members of Congress, the Massachusetts Republican Party today called on Professor Elizabeth Warren to return thousands in tainted campaign contributions from convicted insider trader George Soros. Last week, Soros’ conviction of insider trading was once again upheld in international court.

Last October, Soros hosted a $1,000-a-head fundraiser for Warren in New York, and according to FEC reports, Warren has taken $11,500 from Soros and his family. Warren has made criticism of Wall Street money in politics a staple of her campaign stump speech, despite admitting that she accepts their donations, but only from good Wall Street donors who want reform.

“Scott Brown deserves credit for taking a leadership role in closing an ethics loophole with legislation that bans members of Congress from insider trading,” said Alleigh Marre, spokeswoman for the MassGOP. “Now, Elizabeth Warren needs to demonstrate her commitment to ethics in government by returning tainted campaign contributions from convicted insider trader George Soros and his family.”

Last Week, George Soros’ Insider Trading Conviction Was Upheld. “Billionaire financier George Soros lost his bid Tuesday for an appeal from The European Court of Human Rights, which declined to review its previous upholding of the defendant’s decade-old insider trading conviction despite Soros’ claims that a French court violated his rights.” (Amanda Bransford, “European Court Denies Soros Insider Trading Appeal,” Law 360, 3/29/12)

Warren Has Admitted She Takes Wall Street Money. “Warren said that although a majority of her campaign donations have come from small contributions of $100 or less, there are a few Wall Street contributors among the crowd.” (Robert Rizutto, “Democratic U.S. Senate Challenger Elizabeth Warren Comes Out Swinging At Dorchester Town Hall Discussion,” Springfield Republican, 1/3/12)

In February, Warren Said She Only Takes “Good” Wall Street Donations. “WFXT’S SHANNON MULAIRE: “You talk about fighting against Wall Street, but you’ve also taken money from them in terms of your donations.” ELIZABETH WARREN: It’s because there are some people on Wall Street – some very good people on Wall Street – who look around and say, ‘We do need some rules here, we need some transparency …’” (WFXT “Morning News,” 2/14/12)
